Carbon-Arc Gouging (Video)

[Rock knocker]

You gotta wonder why anyone would say that arc gouging was a waste and laughable. What kind of trade would laugh at something like that.

[Rock knocker]

I could see Bostick questioning using a medium sized CV machine as a CAC power source, but he seems to be comdeming all CAC as a process. Which is a little ignorant

[joshuabardwell]

Machines like some of Lincolns Powerwave- Invertec with a Gouging setting are all CC. Once again I cannot watch a video where the info, and setup is all wrong..

Not sure what the problem is. They acknowledge clearly in the video that they ought to use a CC machine, but since they don't have one, they use a CV machine set on max "in a pinch". The idea is to give a general overview of the process for people like me who had never seen it before.

[Lanse]

You and mister "I've never done this before but here's my opinion on it anyway"

Bahahaha, yeah, you two have fun with that

That reminds me... I meant to figure out the ignore list on this here site :wink:

[ManoKai]

@ Lanse - cool look at A-CAC. IRT to the poster with all the WhizDumb, this: "the office is a dangerous place from which to view the world" Rip It!

[soutthpaw]

LMAO!

For someone who hasn't used one or seen the benefits, it's impossible to understand.

There's nothing like running one off a big Diesel engine drive with the big carbons. Cuts thru 2 1/2" flange H beam like butter.

Now there is something I wanna try! If I come across a monster 3 phase machine for pennies (i have bought a couple in the past for scrapping under $100 each) I would buy it just to try this.. of course I would need an arc air torch too.. I am thinking my TA predator at 10KW 3phase 460 could power a big machine to do this. If I had a torch I would definitely try it off the old 330ABP at that will push well over 400amps

[Scott Young]

Air arc is anything but useless. I describe it like plasma cutting with depth control. The more I use it, the more I wonder why I don't use it more! Too bad you weren't closer lanse, I can't wait to try these.

You are going to need a lot of machine for those 3/8s they start out at 450 amps and go up from there up to over 600 amps.

[Scott Young]

Great idea. I could make a living correcting all the misinformation posted on your dog, and pony show.

I think Sam has beat me to the punch on that deal

See my sig line.

In the field I work in people would laugh their *** off at you for bringing out this rig. I can do just as well with a torch and a washing tip. different strokes different folks I guess.

Wow. I will sign over a weeks pay to see you wash a bevel in some 9 crm, inco, hastalloy, or stainless with a torch and wash tip. A oldtimer told me once... you have to be able to take the metal off just as good as you can put it on if you want to be a real hand.

[Scott Young]

See my sig line.

you added that sig line after I posted didn't you! Just kidding. I am blind in one eye and can't see out of the other.

You will enjoy running those. try the flat carbons. talk about a swath of metal being taken out. we had round oval and flat. I don't know what the ovals were for they all erased metal. I preferred the flats when I had to remove metal to get to impurities on a butt joint. for everything else I liked the round. If you run the in electrode negative, you can get a really sharp point. if you run in electrode positive you will get a round wide point. they are a lot of fun when you have plenty of air. be sure of your surroundings though. Satan doesn't have any thing on this as for fire starting. I also like the O2 lance or slice wands.

[Pressure_Welder]

Steam or hydro-power? I ask because if you're a Boilermaker, they work on both by agreement

totally different turbine setup, the turbine that our coal fired unit spins basically.... best way to describe it looks like jet engine fan blades, and is spun with superheated high pressure steam. The one in the picture I am helping train a new welder at one of our northern dams on how to do cavitation repairs, it of course is propelled by high velocity water

as for bostick, hes apparently an internet tough guy...... carbon arc absolutely has its place, almost every pipeline truck that runs around here is setup with air vantages. theres specific REPAIR crews that all they do all day is gouge out busted welds and re-do them. Only real thing they use a torch for is cutting bevels, and even then a lot are using air powered bevelers now.

As for Lanse, I think he is catering to a certain crowd here on this website... there are a lot of do it yourselfers, weekend warriors, or beginners looking for some basic tips on some welding process's, I think hes doing a great job for those people and he should continue! Having said that for those of us who are in the professional side of things I wouldn't expect any of us to take any learnings from him so coming on here and bashing him for making his videos that are geared towards an rookie/novice audience is childish and a true judge of character.... only advice I would have is to work on consistency! continue your great work.

Ahhhhh yeahhhhh we got a winner

Thanks Pressure Welder, I really enjoy your work :wink:

So it's settled I guess......really shouldn't run these on CV.

And turning the MIG machine up all the way does not make it Constant Current far as I know

My gut feeling is that you'd have control issues using CV. CC allows for changes in voltage as amperage is decreased/increased by arc length. It's how we're able to fill gaps using a stick machine.......simply increase arc length to reduce "heat" (amperage), while increasing voltage.

The MIG machine was limited to around maybe 28-35 volts I believe.

Small engine drive like the Ranger will produce 80 OCV wide open, but only produce 25 volts at 100% duty cycle. So I'm wondering what the realistic voltage/duty cycle is as related to gouging.

And I'm not sure that air consumption isn't an issue with setups like most people have.

A buddy from Up North is sending me a K2000 to play with, and decide if I feel it's worth buying one for my own use.(Thanks Scott)

I'm gonna see just how good this thing is for what I mainly do. If it isn't the best thing since sliced bread it ain't gonna be on my shelf

I should move about 120mi North to Missouri SHOW ME!! Till I do it hands-on I'm not convinced.

[blackbart]

It doesn't take a lot to become halfway profecient at it. I bought 3 box's of 3/16" carbons on ebay. They seem to be max size for my trailblazer.

[farmersamm]

Far as the videos go.................

I'd take great umbrage at a wet-behind-the-ears truck driver trying to give tips to another wet-behind-the-ears newbie truck driver. Doesn't make sense. But that's just me

Kind of like asking your 3yr old kid sister how to reline a set of brakes (Unless you have a really GIFTED kid sister)

Moving pictures are powerful. Just look at the fact that the news media makes most people thing that out country is on the verge of socialism, communism, and nudism They say it, and the idiots believe it Same same with politicians, they lie enough that eventually the idiots believe them

Character?? I may not have character, but I like to think that I AM a character

Besides, my buddy ain't gonna stop making vids...........Sarah Palin still makes speeches regardless

I think you'll like it as long as you can use it where you won't start half the county on fire - major sparks.
Even my kids back up

For cutting out crappy welds, or cutting welds to replace stuff, it's great - much faster than grinding.
Supposed to be good for putting a fast bevel on heavy stuff - but I haven't tried it for that yet.

I'm not super experienced with them - just enough to see the benefits when I can use them.
Actually wish I had a smaller version.

Air powered bevelers? your out of your god damn mind sir.

Guess you've never seen a water wall boiler or tube-bank.

[ThorsHammer]

I've come to the conclusion that Bostick is an internet troll. coming in to start fights with well known, knowledgable, and well respected forrum members. and with a whopping 25 posts under his name. could very easily be someone who was politely, or possibly not so politely asked to leave in the past. and because of this, I'm going to just disregard his comments, as it's fairly obvious that he either is just here to start fights, or is so far under a rock that anything that he doesn't use personally needs to be insulted and disrespected. Hopefully he can open up his mind to using other tools and methods instead of bashing others for using them.

[Rock knocker]

You're right

[Pressure_Welder]

[QUOTE=Bostick101;2783951]Air powered bevelers? your out of your god damn mind sir.[/QUO

lol your cute... I must be in my own little world when were replacing sections of water wall and beveling upwards up 100 tubes.... with this magical crazy thing called air that comes out of a hose! it must be magic.

but I guess if I was a real welder I would just put a bevel on with a torch right?

heres a video to prove how much of an idiot iam

Hahaha..... ya but I built that all with a wash tip on my torch

They are sitting right there with a PT-225! pick the size right rods and torch for it. Figure it out your equipment before show how smart you are about using it. Stupid in every way..
